Can a wealth tax be successful?

Countries that have used a wealth tax

With many countries struggling with high budget deficits and national debts, it is an increasing challenge to find ways to pay for government spending without further increasing debt levels or increasing general taxes. Some governments are looking at a wealth tax on the richest in society.

Wealth taxes are popular amongst the general population because they focus on raising tax revenue from the richest in society, which means ordinary people do not have to pay more tax, and it reduces income inequality.

A wealth tax is a levy on the total value of an individual's assets rather than their income. This might include the value property, shares, bonds and other assets a person might own. Unlike capital gains tax, which is paid on the increase in the value of an asset when it is sold, wealth tax is an annual tax based on the value of a person’s assets.

A one-off wealth tax, often used after major crises, could also be an option to raise a substantial amount of revenue in one go. For example, Argentina used a one-off tax on individuals with assets over $2.5 million to fund pandemic-related spending.

Some countries are currently using a wealth tax. These countries include France, Spain, Norway, Colombia and Argentina. The French experience with a wealth tax provides insight into its consequences. The French government first introduced a wealth tax in 1981. It was updated in 1989 and further amended by Emmanuel Macron’s government in 2018, changing the tax from all assets to focus on real estate.

The French experienced several issues with their general wealth tax. It triggered significant capital flight, as wealthy individuals relocated and moved assets abroad to avoid taxation, often to countries beyond the reach of French authorities. Despite targeting the richest households, the tax generated relatively little revenue and incurred high administrative costs, resulting in minimal net fiscal benefit. Additionally, it had a discouraging effect on entrepreneurship and investment within the French economy.

The change from a general wealth tax to a real estate tax in 2018 has addressed some of the general wealth tax's problems, but it still faces some of the same issues, and there is no evidence that it generates significant revenue.

A wealth tax is a possible solution to raising funds for government expenditure in times of high debt levels. The evidence suggests that it is a popular option, but the results of a wealth tax are mixed, and it is probably not a ‘silver bullet’ solution to increasing tax revenue.
